I Had Just Gotten My Engine Rebuilt And Was Wondering How Long Before I Can Rally Romp On It

 

I'd give it 500 - 1,000 miles, then change oil and go.

 

Would That Go For Towing As Wel

 

yup that'll work

 

Where do you guys come up with this 500-1000 mile "break in" stuff?

What do you think the big trucks do after a rebuild? They certainly don't drive around getting 6.75 mpg and waste almost $400 in fuel just to "break in". I know, I know $385 isn't a lot when you consider a $6000-$10000 job, but they do. As soon as it leaves the shop they hook to their next load immediately and don't think twice. Now, they make the first couple oil changes a little earlier than normal, but that's it.

Each of our Sterling service trucks have 260/660 ISB's in them and average between 10-12mpg at just shy of 30K lbs. . If I drove all 4 of them around to "break in" for 1000 miles I would have spent another $1040 in fuel alone, not to mention the payroll expense of having my guys drive around aimlessly. (64 hours to drive 4 trucks, 100 miles each @ 60mph) The thought of that is absurd and quite a few successful transportation companies would be going backwards if they used that philosophy. Also, on second thought, what about the needless liability exposure of being on the road? How silly would you feel if you were involved in an accident during this ominous "break in" period.

 

well hes going to have to drive it anyways, so just for peace of mind take it easy for the first 500 miles or so. it'll be easier on it

 

this might be a lil off topic, but... what constituted doing an engine rebuild? all i ever hear is its cheaper just to swap one in. how did you do in your CTD enough to warrant a rebuild?

 

53 blocks all i have to say

 

6 inch crack this is all before i had anything done to the truck and no towing ,it also had 110,000 on it and dodge and cummins both turned there head it only cost me 2,800 to have it rebuilt plus another 4,000 for all of my mods and a 2 year warranty

 

Now, I can see the taking it easy on it part, but not babying it. There's just no point.

If you feel better driving around wasting fuel then by all means do it, but nothing bad is going to happen in the first 500-1000 miles that couldn't happen at 5000-10000+. And if something does happen early on you would at least be under some kind of warranty...... better to find out if there are any weaknesses as soon as possible and on someone else's dime and time!

 

Thanks Smokindog

 

our procedure for overhaul is not let the engine sit there at idle more than 5 mins. and only long enough to check for any leaks.... then it goes on the dyno and run hard at max H.P. to max Torque alternating to help with ring seating. for at least half and hour with Blow-by tester hooked up. once that is done it is given to the cust. to use as he normally used it. there is not being easy on it at all. one of the problems I have is when a new tech start working for us and does a dyno run and I will ask him how was the horsepower, he tell me that he got 200 h.p. on a engine that put out 565 h.p. I have to tell them that ain't cutting it and go back on there and max it out, then they have that look on thier eyes and I assure them that if they did the job correctly.... they should have no fear

 

when i had my 1991 mack ch613 overhauled i was told run it hard and change the oil at 5000 miles the 1st time then go back to 10 or 12000 mile oil changes just my $0.02

 

I want to know where he got it rebuilt for only 2800..........
